Good question. Answer is... I have a feeling it should just work anyway and find a DC which is alive.

Your biggest concern in this scenario should be DNS - if you run DNS on your DCs (to get directory-replicated integrated DNS) and your DCs are down, how will a client be able to even query to get the address for another name server?

So it would just find a DC which is alive? Is there a way to control it like specify which DC?

This is a good question. My DNS are running on my DCs. So how will a client query addresses if DNS/DC is down?

It won't. Or rather, it will try to query the DNS servers it knows about, based on what DHCP told it in the first place (assuming you are using DHCP).

It can use its own cache stored up before the DCs fell over, but when it tries to contact a DC it already knows about and fails, it will need to find out where another one is, and if there are no DNS servers available for it then you are in trouble.
